Ammonia Combustion
Ammonia solutions for the UK construction industry
The UK government will fund a new red diesel replacement project from engine developers MAHLE Powertrain and partners Clean Air Power and the University of Nottingham. The trio will demonstrate decarbonisation of heavy duty engines using ammonia and hydrogen fuel, or a blend of the two. Fortescue Future Industries and Liebherr are also involved in the decarbonisation of the UK construction sector, with agreements on hydrogen fuel supply & engine development signed last October. Fuel cells also enter this mix, with AFC Energy currently rolling out off-grid, ammonia-powered gensets on construction sites in London and Madrid.
DoE funding for ammonia energy
As part of a new round of funding announcements, the US Department of Energy will contribute nearly $10 million to three significant ammonia energy initiatives:
- GTI Energy (a recent rebrand of the Gas Technology Institute) will develop a prototype ammonia-powered gas turbine.
- Raytheon will develop and demonstrate an ultra-low NOx emitting ammonia combustor module for gas turbines.
- And 8 Rivers received backing to complete a pre-FEED study for its CCS ammonia project in Evanston, Wyoming.

Ammonia combustion engines: latest research
The journey from the laboratory bench to the shop floor continues apace in 2021, as researchers deepen their understanding of ammonia combustion within engines. The team at Université d’Orléans has published several pieces of research already this year, with interesting results on operating limits, spray characteristics and flame propagation.
